Answer:
0.5 hour
Step-by-step explanation:
Given
Speed of Dina = 10 km/h
Distance = 20 km
So the time Dina taken to complete the track is:
The time taken by Dina is 2 hours. As masha started with dina but she was 4 km of the path left to cycle,
her distance covered in 2 hours was:
So we know the time and distance:
Now,
We have to calculate the time that will be needed by MAsha to complete the track:
As we know the speed and remaining distance
Masha needs 0.5 hour to complete the track ..
If we let
x as the length of the pen
y as the width of the pen
The area is
xy = 2000
The perimeter is
P = 2(x+y)
From the area
y = 2000/x
Substituting
P = 2(x + 2000/x)
which is the equation used to find the least amount of fencing possible.<span />
Answer:
if there was a 15% discount, then you paid 75% of the original price. Since we don't know the orginal price, we will assign it the variable x. Change 75% to a decimal. The equation would be:
.75x = 208.25 To get the variable by itself, divide each side by .75
.75x/.75= 208.25/.75
x = 277.6
The original price of the suit was $277.6
I hope this helped you.
